MACHINE FOR SIZING PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 316,129, dated April21,1885.

Application filed January 29, 1884. (No model.)

To all whom it may concern.-

Be it known that I, AMOS DICKERMAN, a citizen of the United States ofAmerica, residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inMachines for Sizing Paper Tubes, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to machines for sizing paper tubes forcartridge-shells so that they will be uniform in size and lit the boreof the gun.

The invention consists in novel combinations and new parts, as the sameare hereinafter more fully set forth and claimed.

Figure 1 is a perspective view of the machine. Fig. 2 is a centralvertical section of the slide and of a portion of the turret-head. Fig.3 is a rear elevation of the circular disk. Fig. at is a View of a papertube. Fig. 5 is an enlarged side elevation of a part of the frame with afeeding attachment secured thereto. Fig. 6 is a cross-section of thisattachment, and shows one of the pieces for holding the tube. Fig. 7 isan enlarged plan view of this attachment and parts connected to it. Fig.8 is a plan view, partly in section, showing the means for revolving theturret-head.

To enable others to make and use my machine, I will describe it indetail, and its mode of operation.

The oblong frame Ahas two flat strips with beveled edges, which, withthe beveled surfaces on the parts to which they are bolted, formV-shap'ed ways 0 for the slide D. The slide D has an opening, E,lengthwise through it, and V-shaped edges F, which fit in the ways 0 ofthe frame. It also has the projection R, through which a pin passes tohold one end of the connecting-rod to the slide. The shaft G turns inbearings in the slide, and to it the turret-head H and ratchet-wheel pare fastened. A hole, 1', is made in the slide for holding the pin j,which is forced successively into equidistant holes Z Z in the lowerpart of the turret-head and prevents its turning.

It will be understood that the base of the turret is provided with aseries of these holes Z Z, arranged at regular intervals. The lower endof the pinj within the hole or recess t is supported by a spring, k, asshown in Fig. 2. A'lever, m, enters a slot in the pin j. This lever ispivoted in an opening in the slide, and to its outer end is journaled aroller, a. An

inclined way, 0, is pivoted on a stud in the frame, and its thin end issupported by a pin in such a manner as to allow the roller n to run upthe way and withdraw the pin j from its engagement with the turret.turret is turned, the roller 12 will have passed beyond the way 0, andthat end of the lever at will have dropped low enough to cause itsopposite end to elevate the pinj into the next hole Z, and the roller itwill pass under the inclined way 0 as the direction of the movement ofthe slide is changed. The pawl q turns on a stud in the frame, and itswide and heavy end rests on the frame or apin in the frame. As theratchet engages the pawl as the slide moves toward it, the shaft G andthe attached parts are turned an eighth of a revolution. As'

the slide moves in the opposite direction, the pawl slips over the underside of the teeth on the ratchet instead of over the ends in the usualmanner.

When the These devices are so arranged and timed 7 head the ratchetengages the pawl and turns the shaft'G. The circular disk U and thegear-wheel W are fastened on the shaft or, on theouter end of which isacollar (not shown) .to hold it in the frame y, in which it turns. Thedisk U has a dovetailed groove, 25, in which the slide V is adjusted toregulate the movement of the slide D. It is held in place by a boltpassing through the disk with a nut on its end. the slide and forms apin for holding one end of the connecting-rod S. The shaft of thesmaller The other end projects in front of j gear-wheel .2 turns in abearing in the frame and carries two pulleys, 2', one of which is looseon the shaft. The turret-head H has eight round arms, h, of such sizethat they will snugly fit into the paper tubes. These arms are broughtin line of the direction of the die It by the pawl and ratchet. The dieIt is made of steel and preferably in two pieces less than semicircles.so that the parts may be brought nearer each other as they wear. It ishardened and poli and is still turning.

ished. The size of the hole in the die isrthe size to which the tubesare to be reduced. It is fastened in the spindle m, which carries adriving-pulley, 0, and turns in the headblock a.

The machine as thus constructed is operated as described, and the tubesmay be placed upon the arms of the spider by hand; but when desired anattachment shown in Figs. 5, 6, and 7 may be employed to hold the tubein position to be received upon an arm of the spider as the latter isthrust away from the die. This attachment will now be described. Theattachment A, Fig. 5, is bolted to the end of the main frame oppositethe die k, and to it is hinged or pivoted the abutment f by means of thebolt The pieces I), that are pivoted to plates 0 on this part of theframe, have the curved grooves or notches e, and are made in the formshown in Fig. 6. They are held in position by the springs d. In thesegrooves e the paper tubes are placed. The pieces b may be varied inconstruction for example, the springs may be omitted and a central partof the piece may extend down ward below or under the grooves and be madeheavy enough to hold the pieces in position, or two thin flat springs,bent in the proper form. and inserted in the frame, may be substitutedfor each piece. The abutment f is pivoted on one side of the frame, asshown at g in Fig. 5; but it may be pivoted or hinged in various waysforexample, an arm attached to the frame may extend upward and over it andthe abutment be hinged to the arm. The object of the pivot g is to allowthe abutment to move out of the way as an arm of the turrethead passesover this part of the attachment. The spring 13 is fastened to the frameand comes against the side of the abutment.

The several parts of the machine being constructed as above described,its operation is as follows: As the turret-head moves toward theabutment an arm of the head passes up one of the grooves e in the piecesI). \Vhen the arm reaches the abutment under the movement of the slideD, that carries the' turret, the ratchet reaches the pawl and the arm isturned away from the abutment; but the turret-head is still moving inthe same direction The result is that the arm next to the arm that hasjust mov'edfrom over the grooves 6 comes against the side of theabutment and turns it over toward the spring 2" sufliciently to let thearm come over the groove 6. The pieces I) are tipped down by the arm andthe arm passes over them. As the motion of the turret-head is reversedand the arm holding the abutment to one side moves away from theabutment toward the die the spring forces the abutment back to itsposition. Such is the action of the parts mentioned when there are nopaper tubes in the machine; but when the reciprocating turrethead-isnear the die a paper tube is placed in one of the grooves e, and as thehead comes toward the abutment an arm of the head enters the tube, andas the abutment prevents endwise movement of the tube the arm is forcedinto the tube. XVhen the tube, by the reciprocating and rotary movementof the head, passes through the rapidly-turning die, the die makes itsouter surface hard, smooth, and glassy.

What I claim as new, and desire to secure by Letters Patent, is-

1. The turret-head II, provided with the arms 71., and having anintermittent rotary movement and a reciprocating movement cor respondingto the movement of theslide, in

combination with the revolving die, as set.

forth.

2. The slide D and shaft G, arranged and turning in the slide, andcarrying the ratchetwheel and turret-head, in combination with the pawlpivoted on a stud in the frame, asset forth.

3. The lever m, pivoted to the slide and carrying the roller 02, incombination with the inclined way 0, pin 9, and turret H, having aseries of holes, Z Z, for the reception of said pin, as set forth.

4.. The combination, with the table A, slide D, and turret H, havingmeans for holding the papertubes, of the feeding attachment A andabutment f, as set forth.

5. The combination of the table A, having beveled ways 0 O, the slide D,turret H, having arms 71. h, the rotary die It, the feeding attachmentA, pivoted abutment f, having spring 4;, and mechanism for imparting areciprocating and rotary movement to the turret, substantially asdescribed.

In testimony whereof I aiiix my signature in presence of two witnesses.
